edition of the NEC, National Electrical Code NFPA-70 which may be
ordered from: National Fire Protection Association, 1 Batterymarch
Park, Quincy, MA 02269.
3. If after reading this manual you have any questions or do not
understand any portion of the instructions, call the local utility or the
manufacturer whose name appears on the rating plate.
4. Carefully plan the place where you are going to put the water heater.
INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES
ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN
THE FIELD INVOLVED. PLUMBING AND ELECTRICAL WORK ARE
REQUIRED.
Examine the location to ensure the water heater complies with the
“Facts to Consider About the Location” section in this manual.
5. For California installation this water heater must be braced, anchored,
or strapped to avoid falling or moving during an earthquake. See
instructions for correct installation procedures. Instructions may be
obtained from California Office of the State Architect, 400 P Street,
Sacramento, CA 95814.
6. Massachusetts Code requires this water heater to be installed in

TYPICAL INSTALLATION

HEATER IS INSTALLED IN A
CLOSED WATER SYSTEM.
MIXING VALVE USAGE
Water (Potable) Heating: All models are considered suitable for
water (potable) heating only.
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to a
temperature which will satisfy space heating, clothes washing, dish
washing, and other sanitizing needs can scald and permanently injure
you upon contact. Some people are more likely to be permanently
injured by hot water than others. These include the elderly, children, the
infirm, or physically/mentally handicapped. If anyone using hot water in
your home fits into one of these groups or if there is a local code or state
law requiring a certain temperature water at the hot water tap, then you
must take special precautions. In addition to using the lowest possible
temperature setting that satisfies your hot water needs, a means such
as a *mixing valve, shall be used at the hot water taps used by these
people or at the water heater. Mixing valves are available local plumbing
contractor. Consult a Qualified Installer or Service Agency. Follow
mixing valve manufacturer’s instructions for installation of the valves.
Before changing the factory setting on the thermostat, read the
“Temperature Regulation” section in this manual.

LOCATING THE NEW WATER HEATER
FACTS TO CONSIDER ABOUT THE LOCATION
Carefully choose an indoor location for the new water heater, because
the placement is a very important consideration for the safety of the
occupants in the building and for the most economical use of the
appliance.
Whether replacing an old water heater or putting the water heater in a
new location, the following critical points must be observed:
1. Select a location indoors as close as practical or centralized to the
water piping system as possible. The water heater should be
located in an area not subject to freezing temperatures.
2. Selected location must provide adequate clearances (4”) for servicing
parts such as the thermostats, drain valve and relief valve. Adequate
clearance for servicing this appliance should be considered before
installation, such as changing the anodes, etc.
Installation of the water heater must be accomplished in such a manner
that if the tank or any connections should leak, the flow will not cause
damage to the structure. For this reason, it is not advisable to install the
water heater in an attic or upper floor. When such locations cannot be
avoided, a suitable drain pan should be installed under the water heater.
Drain pans are available from your local plumbing contractor. Such a
drain pan must have a minimum length and width of at least 2 inches
(51 mm) greater that the water heater dimensions and must be piped to
an adequate drain.
Also, the water heater must be located and/or protected so it is not
subject to physical damage by a moving vehicle.
INSULATION BLANKETS
Insulation blankets are available to the general public for external use
on electric water heaters but are not necessary with this product. The
purpose of an insulation blanket is to reduce the standby heat loss
encountered with storage tank heaters. Your water heater meets or
exceeds the National Appliance Energy Conversation Act standards
with respect to insulation and standby loss requirements, making an
insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater, you
should follow these instructions below. Failure to follow these
instructions can result in fire, serious personal injury, or death.
•
Do not cover the temperature and pressure relief (T & P) valve with
an insulation blanket.
•
Do not cover the instruction manual. Keep it on the side of the
water heater or nearby for future reference.
Do obtain new warning and instruction labels for placement on the
•
blanket directly over the existing labels.
INSTALLING THE NEW WATER HEATER
OPTIONAL WALL MOUNTING
WALL CONSTRUCTION AT THE POINT OF THE WATER HEATER
INSTALLATION MUST BE CAPABLE OF SUPPORTING AT LEAST 200
POUNDS.
As an example: if the water heater is to be installed on a wall of
gypsum board (dry wall) or other material not capable of supporting
the water heater filled with water, additional bracing will be necessary.
Two possibilities are shown, see Figure 3.
1. Using two sheet metal screws supplied, secure the top mounting
bracket to the top of the water heater.
FIGURE 3.
FIGURE 4.
2. Using the remaining two sheet metal screws provided, secure the
bottom mounting bracket to the bottom of the water heater.
